The smc PENTAX -FA 77mm F1.8 Limited lens is specifically designed for portrait photography and accurately reproduces the tones, colors and texture of the subject's skin, clothes and accessories as well as assuring an excellent rendering of highlight and out of focus areas.
The smc PENTAX-FA 77mm f/1.8 Limited from Pentax is a short-telephoto prime well-suited for portraiture. The optical design pairs with a bright f/1.8 maximum aperture to promote greater control over depth of field for using selective focus and the seven elements in six groups design helps to realize accurate tone and color rendering. This lens also uses the Fixed Rear Element Extension (FREE) focusing system to maintain image quality, sharpness, and clarity throughout the focusing range, from 2.3' to infinity.
The design was based on the numerical evaluation by various testing instruments and also incorporates advanced evaluation using actual images. The result is an appropriate softness at aperture opening, and as the aperture closes, enables sharp imaging performance and rendering that provides a sense of space, gradations, and three-dimensional feel.
This lens uses the FREE system that moves only the front group while keeping the rear group stationary in the lens system when focusing. This enables stable imaging performance from near to far distances.
The lens body uses an aluminum material for providing a design with a sense of elegance and precision. The camera body uses "finger points" made of a deep purple Shippo-yaki material for providing a firmer gripping sensation.
